渤海湾盆地的油气勘探已经进入成熟阶段,寻找有潜力的勘探领域或目标日益困难,由于盆地形成时的断裂作用,低凸起在盆地内分布广泛,并成为盆地内的主要油气聚集带。与低凸起有关的油气藏类型多,含油层系多,油气聚集规律复杂。过去的勘探主要针对低凸起的单一目标进行勘探,忽视了对凸起含油气的整体认识和评价。低凸起作为一个勘探目标,其勘探程度并不高,近几年的勘探实践证实,低凸起仍具有巨大的勘探潜力。 Oil and gas exploration in the Bohai Bay Basin has entered a mature stage and it is increasingly difficult to search for potential exploration areas or targets. Due to the fracture at the time of basin formation, low protuberances are widely distributed in the basin and become the major hydrocarbon accumulation zone in the basin. There are many types of reservoirs associated with low protuberances, more oil-bearing formations and complex hydrocarbon accumulation. In the past, exploration mainly focused on single targets with low bumps, ignoring the overall understanding and evaluation of the raised hydrocarbon. Low bump as an exploration target, its exploration is not high, exploration practice in recent years confirmed that low bumps still have great exploration potential.
